METALLIC ABRADANT.

Application filed May 13, 1927. Serial No. 191,054.

This invention relates, generally, to a novel construction of metallicabradant which is suitable for use as a scouring, scraping and cleaningagent.

Heretofore ametallic material known as steel wool has been commonly usedas an abradant, this material comprising a mass of comparatively finesteel filaments entangled together. This steel wool possesses butalimited efficiency as an abradant, since the steel filaments of whichit is composed consist in relatively fine wirelike elements furthermore,the metal steel easily corrodes or rusts, and when used will, in a veryshorttime, break or splinter off, the resultant particles or splintersoften penetrating the fingers to the great discomfort of the user, andbeing likely also to lodge in cooking utensils, to thence find their wayinto food so as to be likely to be taken into the human system at therisk of causing physical disturbances.

. It is the principal object of this invention to provide a novel formof metallic abradant, which, .due to its peculiar structural character,furnishes an improved abradant possessing great abrading and scrapingefliciency; and, furthermore, when the novel form of abradant is made ofcopper or other non-rusting metal, obviates the above referred toobjections incident to the ordinary steel wool abradant.

Other objects of this invention not at this time more particularlyenumerated, will be clearly understood from the following detaileddescription of the same.

The present invention is illustrated in the accompanying drawings, inwhich 2-- Figure 1 illustrates a mass of the novel abradant madeaccording to and embodying the principles of this invention; Figure 2shows in perspective on a large scale a metallic filament of the novelform and structure provided b this invention; and Figure 3 illustrateste manner in which the novel metallic filament is entangled when formedinto a desired mass.

Referring to the drawings, the novel abradant comprises a flatribbon-like metallic wire or strip a, with the body thereof transverselyfolded upon itself in zig-zag fashion to provide a. multiplicity ofcomparatively sharp scraping edges 6 and angular abrading points orcorners c, all as shown in Figure 2 of the drawings.

The wire or strip body thus formed pro- "vides throughout its length amultiplicity of comparatively sharp angular projections which furnish ahigh degree of scraping or abrading efficiency.

The wire or strip body having the described zigzag formation may beproduced in a single contmuous run of any desired length, and thereuponmay be interfolded, looped and entangled upon itself to form aninterentangled mass or a plurality of lengths of the so formed metallicwire or strip may be interlooped, mtertwisted and entangled together toproduce the desired more or less compacted mass or abradant body shownin Figure 1 of the drawings.

It will be at once apparent that an entangled mass of the zigzag formedwires or strips when compacted together will form an abradant bodyfurnishing literally hundreds of sharp abrading points and ed es, whlch,by virtue of the tortuous intertwistmg entanglement of the filaments,are presented or projected in all possible directions I As aconsequence, when applying the thus formed mass of abradant against andrub bing the same upon a surface to be cleaned,

scraping points will be effectively brought into play, no matter whatthe direction of movement imparted to the mass may be; and at the sametime, by virtue of the great multipllcity of scraping edges and points,which are engaged with such surface, the abrading or lfcrapingefliciency will be exceedingly It will be understood that the flat orribhon-like strip may be given formations other than the exact zlg-zagformation shown, as long as the object of producin a multiplicity ofscraping and abrading e%ges or points throughout the length thereof isattained.

I prefer to make my novel abradant material of copper or othernon-rusting metal, since such metal is more sanitary, less likely toweaken and break or splinter off. It will be understood, however, thatso far as the novel zlg-zag formation of the filaments are concerned,that such formation would be equally efliclent regardless of theparticular kind of metal employed, hence, in the broader aspects of theinvention I do not limit myself solely to the non-rusting metals. I mayalso emp 0y a metal which can be more or less hardened or tempered,whereby the effectiveness of the scrapin edges and abrading points isconsidera ly increased, and less tendency to deform out of desiredzig-zag or equivalent normal shape is likely.

Having thus described my invention, I claim 1. A metallic abradantmaterial comprising a flat ribbon-like body having deformationsthroughout its length formed by bending said body along lines extendintransversely of its width, said deformations being adapted to provide amultiplicity of comparatively shar scraping elements extending from saidbody.

2. An abradant material comprising flat ribbon-like metallic wireinterfolded upon itself throughout its length along lines extendingtransversely of the width of said wire and arranged in substantiallyzig-zag formations to provide a multiplicity of comparatively sharpabrading projections.

3. An abradant material comprising flat ribbon-like metallic wireinterfolded upon itself throughout its length along lines extendintransversel of its width and arrange in substantiallyzig-zag formationsto provide a multi licity of comparatively sharp abrading pro ections,the thus formed wire being tortuously involved upon itself to provide anentangled mass from which said abrading projections variously extend inmany directions.

4. An abradant material comprising a mass of intertangled ribbon-likecopper wire, said wire being interfolded upon itself throughout itslength alon lines extending transversely of the widt thereof andarranged to provide a multiplicit of variously projected comparatively sarp scraping elements coinciding with said transverse lines of bend.

5. An abradant material comprising a mass of interentangled ribbonlikecopper wire, said wire being interfolded upon itself throughout itslength in substantially zigzag formations to provide a multiplicity ofvariously projected comparatively sharp abrading projections extendingtransversely of said wire and coinciding with said folds.

In testimony, that I claim the invention set forth above I have hereuntoset my hand this 6th day of May, 1927.
